The formation of these entities has been linked to the Madden-Julian oscillation and Rossby waves. Two of these approach each other and eventually merge in the Fujiwara effect. Often re-curving around the subtropical ridge, their activity peaks in late summer. Reaching a 12 on the Beaufort scale, they rarely form near the equator because the Coriolis force there is too weak to make them spin. Thes
The formation of these entities has been linked to the Madden-Julian oscillation and Rossby waves. Two of these approach each other and eventually merge in the Fujiwara effect. Often re-curving around the subtropical ridge, their activity peaks in late summer. Reaching a 12 on the Beaufort scale, they rarely form near the equator because the Coriolis force there is too weak to make them spin. These systems are ranked by the Saffir-Simpson scale, on a scale from category 1 to category 5. For 10 points, name these rotating storm systems featuring a low-pressure central "eye," historical examples of which include Andrew, Rita, Wilma, and Katrina.
